16. Asynchronous Serial interface (UART2)
16.1
TXD and RXD pin. TXD and RXD pin are also used as the general port. For TXD pin, the corresponding general port
should be set output mode (Set its output control register to "1" after its output port latch to "1"). For RXD pin, should
be set input mode.
asynchronous serial interface (UART2).
The TMP88FW45AFG has a asynchronous serial interface (UART) . It can connect the peripheral circuits through
RXD3 and TXD3 are correspond to P81 and P80 pins as the connection pins with the peripheral circuits in the
